looked into fixing it about 10 years ago, had the name of a guy down south that repaired broken frames (if memory serves he had a track record with JMC's specifically), and just never really had the time to really commit.
i'm going to be slowly parting out the rest of the bike, and i guess at this point if anyone knows anyone who might be interested in a one-owner 3.1XL frame with a busted down tube, i'm open to offers for a new home.
